Dataset for CHExGraph: A Knowledge Graph for Jagiellonian University Cultural Heritage

CHExGraph: Supplementary Materials This repository contains the supplementary materials accompanying the resource paper "CHExGraph: A Knowledge Graph for Jagiellonian University Cultural Heritage." CHExGraph integrates archival, bibliographic, and museum metadata related to the cultural heritage of the Jagiellonian University within a unified CIDOC CRM-based semantic model, enabling cross-collection discovery and analysis. The repository includes: chexgraph.ttl – the RDF/Turtle serialization of the CHExGraph knowledge graph. CHExGraph_Competency_Questions.ipynb – a Jupyter notebook containing the competency questions presented in the article, implemented as executable SPARQL queries against the CHExGraph knowledge graph. The materials are provided to support the reproducibility of the research described in the article. The notebook demonstrates how the competency questions were operationalized as SPARQL queries and can be used to reproduce the evaluation, explore the data model, and serve as a starting point for adapting the queries to other CIDOC CRM-based cultural heritage knowledge graphs.
